The U.S. Department of Energy issued a Section 202(c) emergency order on September 3, authorizing Duke Energy Carolinas to deploy additional generation and backup resources to meet extreme heat-driven electricity demand in North and South Carolina. Peak demand was forecast to reach 22,295 MW on September 3 and 21,773 MW on September 4. Duke Energy added 2,677 MW of capacity and implemented demand-management measures to reduce load by over 400 MW. However, the utility indicated that load curtailments might still be necessary to stabilize the grid.

The emergency order permits Duke Energy to activate specific generating units and coordinate with transmission owners to deploy backup resources as a last resort. This highlights the potential of distributed energy resources, including customer-sited backup generators and batteries, to support grid reliability during emergencies.

Why it matters: The emergency order underscores the increasing risks to grid reliability from climate-driven demand spikes. It also signals a shift toward integrating distributed energy solutions, with implications for infrastructure investment and regulatory strategies across the utility sector.
